Hi I got this error and don’t know what to do.
I have included the rg-to-csv item on the page.
I added the id attribute to the repeating group.
I added the workflow element.
Let me know what you think. Thanks!
Hi @cbray,
Thanks for the screenshot — that error usually means the action is trying to run a .replace on a value that’s null (most often the File name, a header, or a column value that’s expected to be text). A few quick checks that typically fix it:
- Give the action a static File name to test (e.g.,
orders_export.xlsx). - Make sure Columns to export isn’t empty and that any Custom headers list matches the number of columns.
- Confirm the RG’s data source has items at the moment the action runs.
- Ensure the RG has the exact ID attribute used in the action and is on the page/visible when exporting.
- If you’re mapping dynamic expressions, make sure none can be empty or non-text when exported (you can use
:formatted as textor default values). - Update to the latest plugin version and compare against the setup in the docs: Repeating Group to CSV / XLSX Plugin
To help us pinpoint it, could you please share:
- A screenshot of the Repeating Group (Layout + Data tab) showing the ID attribute and Data source
- A screenshot of the Repeating Group to CSV/XLSX element settings
- A screenshot of the workflow action (Download File / Export) with all fields visible
- A short screen recording of the export attempt with
?debug_mode=true, Step-by-step enabled, and the browser console open (so we can see when values become null)
Once we have this information, I will do my best to help you.
